Simple, requires calling function implementation

Here's a pit, here. Read the string do not use the gets function, will read out a space, scanf does not exist this problem.
In addition, to avoid the array output garbled, it is necessary to initialize the string array when defining it.
Recently I used Python to call C programs, so I looked at the way Python calls other programs. Generally speaking, Python calls C/C + + There are two ways, one is to invoke the dynamic link library, that is, the so file, a C-generated executable file. Specifically, depending on the application scenario.
Python invokes the executable file, and in fact executes the commands that were originally executed on the command line in Python.
Specific methods:
(1). Write C + + program with main program MAI
This example shows the Destoon method of calling the text news, which is a very common and practical technique. Share to everyone for your reference. The implementation methods are as follows:
The main functional code looks like this:
{if $DT [page_news]}
It is hoped that the method described in this paper will be helpful to the development of Destoon.
speed.
Three or more of the two methods, which can only be called indirectly by calling a background stored procedure, Access also provides a direct call to send a command directly to the database server using an Access pass-through query.
To establish an Access pass-through query, follow these steps:
(1) Click the Query tab in the Database window, and then click the New button.
(2) In the New Query dialog box, click the Design view option, and then

What's the difference between a phone card and a regular phone?
Advantages: Do not rent phone calls regardless of long-distance telephone, all 0.1 yuan, to answer the national free no roaming
Disadvantages: Caller ID only support Beijing, Hangzhou, which is the location, when you call others, (others on the phone show the address), change the number of trouble, now people's mobile phone number are bound countless accounts, for a mobile phone
We all know that calling other programs in Android is almost always intent, so email is no exception.
In Android, there are three types of intent that call email:
Intent.action_sendto Send without attachment
Intent.action_send Send with Attachment
Intent.action_send_multiple Send with multiple attachments
Of course, the so-called call email, just say that email can receive intent and do these things, may also have other applications to implement the
Stored Procedures | issues
Calling stored procedures in C # is primarily a matter of parameter usage (input parameters, output parameters, return values)It is assumed that Conn is a defined connection, proc is the stored procedure name
1, call no parameter no return of stored proceduresSqlCommand cmd=new SqlCommand (proc,conn);Cmd.commandtype=commandtype.storedprocedure;//tells the execution of the stored procedureConn. Open ();Cmd. ExecuteNonQuery ()
Data | Page We often need to return the data to the calling page, and here is the basic implementation.
Suppose that there are two page selectdate.aspx,calendar.aspx.
You need to make a connection in selectdate.aspx, click to open Calendar.aspx, and then select the date in calendar.aspx to return the selected date to
Selectdate.aspx (hehe, don't know I said understand)
Forget it, look at the code, it's natural to understand.
Yes, and I need a file to
This article illustrates the method of calling the function in the IFRAME frames page in Javscript, this method is very simple, with this method we can achieve the value or modify the value of the IFRAME, the operation is very simple. Share to everyone for your reference. The implementation methods are as follows:
To access the functions within the IFRAME:
Copy Code code as follows:
document.getElementById (' Commentiframe '). contentwi
I got a day today and finally found a solution on the Internet.
Note: The problem is the method of calling the child page in the parent page ...
Parent page: parent.html
Copy Code code as follows:
Sub-page: child.html
Copy Code code as follows:
You can modify the corresponding code according to their own needs ....
This article illustrates the invocation method of SetInterval () and clearinterval () JS functions. Share to everyone for your reference. Specifically as follows:
Copy Code code as follows:
The SetInterval () method can call a function or a calculation expression in the specified period (in milliseconds).The SetInterval () method keeps calling the function until the clearinterval () is called or the window is closed. The ID v
One, the parent window calls the IFrame child window method1. HTML syntax: 2, the parent window calls the child window: MyFrame.window.functionName ();
3, the child window product calls the parent window: Parent.functionname ();
To put it simply, a parent is added before a variable or function that is invoked in a child window. That's fine.
4, the parent window page Source:
Copy Code code as follows:
5, child window page:
Copy Code code as follows:
